Remediating A Fire Site
Machin and Ehresmann describe remediation of a 15 acre fire site at Fort Huachuca, Ariz. An investigation after the fire showed that all of the debris contained asbestos. Sampling confirmed...
The Application of Microcomputers to Site Location Planning for Emergency Services
The paper presents an overview of the application of FIRE-ROUTER, a microcomputer package designed to assist in fire station location planning. Subjects covered include route finding,...
Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
Debris Flow Potential and Sediment Yield Analysis Following Wild Fire Events in Mountainous Terrain
The Pacific Southwest Inter-Agency Committee (PSIAC) 1968 Sediment Yield Rating Model provides a method to rapidly assess any increase in potential sediment yields following a wild fire...
Predicting Stream Width and Bank Retreat
The width of streams is dependent on the flood flow discharge which varies from year to year, the bank material which varies from stream to stream and reach to reach, the sediment load...
Resistance Consisting of Both Viscous Force and Dispersive Force
A set of specially designed experiments have been carried for studying the resistance of a flow consisting of water and both fine and coarse particles. The viscous force caused by fine...
Stable Channel Analytical Design Method
The Flood-Control Channels Research Program is being conducted at the US Army Engineer Waterways Experiment Station to develop systematic methods for design of stable channels for small...
Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...
Effect of Fly Ash on the Microstructure and Durability of Concrete
The influence of fly ash on the microstructure and durability of concrete was investigated. It was found that the use of 50% fly ash in concrete reduced greatly its resistance to freezing-and-thawing...
Permeability Effects on the Sulfate Resistance of Concrete
A laboratory study was conducted to determine the effect of permeability on the sulfate resistance of concrete containing fly ash. Concrete specimens were moist cured for 7 and 100 days...
Structures Congress Abstracts 1990
Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...
An Overview of Structural Reliability Methods
Recent developments in structural reliability theory and better availability of load and strength data suggest that reliability-based design (RBD) methods should be considered as a practical...
Cambering of Steel Beams
Cold cambering with force in the fabrication shop is an effective and economical method of compensating for deflections of composite beams. Typical beams should be cambered for dead load...
Six Story Tubular Atrium
The author designed an atrium structure with two stair-stepped atriums placed at 45? to the tower 'Figueroa at Wilshire' in Los Angeles, California. This structure...
Cold-Formed Z-Sections Under Axial Load and Bending
The use of cold-formed Z-section members as beam-columns presents some unique design problems which are not adequately addressed in the current design specifications. If these members...
Seismic Response of Flexibly-Connected Steel Frames
The response of typical low-rise steel building frames designed by the 'Type 2 Construction' method to moderate earthquakes is examined. Such frames are often...
Brace Connections for Ductility
Influence of connection design on the seismic behavior of welded bracing members made of double channels is studied in this paper. Shortcomings of commonly used connection details as per...
Strength of Biaxially Crooked Jumbo Columns
The ultimate strength of axially loaded jumbo columns with biaxial initial out-of-straightnesses is analyzed by the finite element method. The analysis makes use of the measured residual...
